This 6-race Shimano CYCLO X Series powered by Boa Technology is back for it's 17th edition!  Each venue is set up to test and challenge the athlete in unique ways, so come November we're able to crown the best cyclocross racer in Colorado!  When it comes time to train get ready for; the power sucking grass of Interlocken, the tight woods of Xilinx, the canal of Sienna Lake, the run ups at Louisville, the 5280 stairs of Valmont, plus many more iconic elements at each venue!


The CYCLO X Series will feature live chip timing!  Friends and family can track the lap splits and action remotely on their smart phones or home computers.  Once athletes cross the finish line they'll have instant access to all their splits at our live TV Timing Tent, located in the event expo!
